The chopper can do so much more than just divide the nucleus into pieces. The chopper can fixate the eye, manipulate tissue, bring cataract pieces to the tip, and dial an IOL into the bag. It can also serve as a way of protecting the posterior capsule by preventing touch of the capsule to the phaco probe even if fluidic surge occurs.
In the brief video presented here, we show a complete cataract case and you can see how often the chopper is used for maneuvers other than chopping. As you become more experienced as a surgeon, you’ll find that you will use fewer instruments in your surgery. My surgical tray has just a few instruments and that is sufficient for 99% of surgeries.
